Influence of Polymer Melt Behavior on Flammability (NISTIR 6588)

March 1, 2000
Author(s)
Thomas J. Ohlemiller, Kathryn M. Butler
As the initial step in a study of the role of polymer melt viscosity in polymer burning behavior, a simpler, non-burning configuration has been examined. Vertical slabs of two types of polypropylene have been subjected to uniform radiative heating on one

Automated Earthmoving Status Determination

February 28, 2000
Author(s)
William C. Stone, Geraldine S. Cheok, Robert R. Lipman
Efforts are underway at the National Institute of Standards and Technology (NIST) to develop automated non-intrusive production measurement systems and procedures for monitoring the status of general earthmoving operations at typical construction sites

Sensor-Driven Inverse Zone Fire Model

February 23, 2000
Author(s)
William D. Davis, Glenn P. Forney
As sensor use in buildings becomes more wide spread, it is possible to use this information as input to an inverse fire model in order to enhance the value of the information available from sensors in both fire and non-fire conditions. Typical fire models

Modeling Study of Ventilation in Manufactured Houses

February 1, 2000
Author(s)
Andrew K. Persily, S R. Martin
The HUD Manufactured Home Construction and Safety Standards (Part 3280, 1994) contain a number of requirements intended to provide adequate levels of outdoor air to the occupants of manufactured homes. In the implementation of these standards, some

New Approaches to the Development of Fire-Safe Materials (NISTIR 6465)

February 1, 2000
Author(s)
A B. Morgan, Jeffrey W. Gilman, Marc R. Nyden, C L. Jackson
Thermoplastic polyetherimide-clay nanocomposites were synthesized from 1,3-phenylenediamine and bisphenol A dianhydride using an in situ approach. Two types of organically treated clays were utilized to synthesize these nanocomposites. The two organically

Using VRML in Construction Industry Applications

February 1, 2000
Author(s)
Robert R. Lipman, K A. Reed
This paper describes initial research using the Virtual Reality Modeling Language (VRML97) in construction industry applications. The modeling of steel structures and construction equipment as objects for inclusion in construction-site world models was

A User's Guide for FAST: Engineering Tools for Estimating Fire Growth and Smoke Transport

January 3, 2000
Author(s)
Richard D. Peacock, Paul A. Reneke, Walter W. Jones, Richard W. Bukowski, Glenn P. Forney
FAST is a collection of fire modeling tools which uses the underlying fire model CFAST and adds the routines of FIREFORM to provide engineering calculations of fire phenomena in compartmented structures. This manual provides documentation and examples for

Advanced Propellant/Additive Development for Fire Suppressing Gas Generators

January 1, 2000
Author(s)
Stephen Fallis, Russell Reed, Paul Wierenga, Gary Holland, Yue-Cherng Lu
The “Advanced Propellant/Additive Development for Gas Generator” project is a collaborative effort between Primex Aerospace Company (PAC) and the Naval Air Warfare Center-Weapons Division (NAWCWD) at China Lake, CA. The objective of this NGP project is to

Chaotic Resonance, Hopping Rates, Spectra and Signal-to-Noise Ratios

January 1, 2000
Author(s)
A Kovaleva, Emil Simiu
We consider a noise-free bistable system with a low frequency signal and a secondary harmonic excitation that causes the systemto experience chaotic motion with a broadband portion of the output spectrum. The signal-to-noise ratio (SNR) is defined on

Combustion Research Studies at the National Institute of Standards and Technology

January 1, 2000
Author(s)
Takashi Kashiwagi, William L. Grosshandler, Anthony P. Hamins, William M. Pitts, Cary Presser, Wing Tsang
The National Institute of Standards and Technology (NIST) is a federal agency within the Technology Administration of the Department of Commerce. NIST's primary mission is to develop and apply technology, measurements, and standards to promote economic
